it lrnoun that l, Sunfire Snivrns. e citizen of the United States7 resid' maha. in the county of Douglas anc Yebraslm9 have invented ce1 useful improvements in Wi which the following is a specificit The present invention relai` Adoor plugs, adapted particule.' -v ing and binding` aile l 7which urring ai. strips me oe lirmly secured to the cement tious bodies her has been diineult io i c. securing' devices.

construction such that it is i and embedded in the cementitious body.

A further object of the invention is to provide a plug of such construction that may be embedded in the Wall or floor structure While the cementitious material is in a plastic state and which may be `approximately located so iat when the nail is substantially driven into the plug it is absolutely essential to have the nail register' accurately with the opening in the plug, the plug being relatively Wide cto admit considerable latitude in the positioning of the nail and also having guiding surfaces et its open end for deilecting and guiding the point of the nail to the interior or the pluv',

. lVith the foregoing and other objects in vieiv, the invention Will be more fully described hereinafter und ,vill be more particularly pointed out in the claim VappendedV hereto.

In the drawing9 wherein like symbols reiter to like or corresponding parts throughout the several views,

Figure l is a fragmentary sectional View through a portion of a. briclr Wall having u iurring strip applied thereto, and showing in section a plug constructed according to this invention in position on in the Wall;

F ig. 2 is a top plan view of a plug constructed according to this invention;

Fig. 3 is an outer elevational end of the seme; and

Fig. et is e side edge vieu7 of the plug.

Referring to the drawing, and iir'st to Fig. l which illustrates one epplicationor use of this plug, i0 and ll designate adjacent portions of superposed bricks in a Wall structure Which are cemented or otherwise suitably secured together by a layer of mortar l2.

The inner faee o't the Wall is provided in the usual manner with a urring strip i8 01"" Wood or the like and to which the laths are usually ett ched. The iurring strip 13 is attached to the Well by neils which are usually driven into the mortar l2 betiveen adjacent bricks.

The plug, according to this invention. and Which Will be described with reference to the upstanding Wall shown in l, comprises a flat bottom l5 and a top' i6, the top rund bottom being preferably mede trom single sheet oie metal which is overturned upon itself intermediate its ends as at 17 at en acute angle', and the top and bottom l5 and i6 diverge from the overturned portion 17 to the open end or mouth of the plug.

rllhe top Wall 17 is provided at its lateral edges with dovvnturned flanges 18 which gradually increase in depth from the reni' edge 17 to the open end of the plug lund lll) The bottom and top 16 are extended slightly beyond the Vforward edges of the flanges 18 and are rolled or bent outwardly away from each other to provide flanges 21 and 22 adapted to lie against the inner 'face of the wall structure and not only determine the position of the plug but also to cor# rectly space the urring strip V13 from the face of the wall.

The top and bottom walls 15 and 16 of the plug may be of desired width to insure the driving of the nail 14 into the plug at any point throughout the width of the plug so that great' accuracy is not necessary in, the

ositioning of the nail 14 opposite the plug. he rolled or rounded edges 23 at the inner ends of the flanges 21 and 22 Vserve as guides to receive therea ainst and deflect the point of the nail 14 s ould the latter be outof vertical alinement with the plug.V

When the device is used in a wall structure, a number of the plugs are embedded in the cementitious material l2 in vertical rows and with the rows suitably spaced apart, such as with the distance ofsixteen inches therebetween, and after the cement or mortar sets, the plugs are firmly embedded therein and held by the prongs 20 from withdrawal from the wall.

The furl-ing strips 13 are now applied to construction where the plug is embedded in a cement body with the plug vertically arranged therein and the prongs 20 firmly anc or the plug 1n lace after the cernentitions body has set. n this case, the furring is in the form of stringers or girders upon which the floor boards are secured.

The plug constructed according to this invention is particularly adapted for use where it is desired to securely hold nails o r the like in mortar, cement, concrete or lilre material.

I do not wish to be restricted to the size, forni, and proportions of the various parts, and obviously changes eouldbe made in the construction herein Vdescribed without departing fromV the spirit oi the invention, it

`being only necessary that such changes tall within the scope of the appended claim.

What is claimed is: v

A wall or floor plug comprising a single sheet oi' metal overturned intermediate ends at a relatively sharp angle and with its sides diverging toward its ends to provide a wedge-shaped throat and at said ends bent outwardly and oppositely to `provide wall abutting flanges, said plug being adapted to be embeddedin a body oit plastic material in a wall or floor and with said iianges abutting againstthe outer 'face thereof, one of said overturned portions of said strip having its edges bent inwardly toward and engaging the other end portion to provide lateral flanges to space and support said sides apart and prevent entrance of the plastic body therebetween, and said other end portion of the strip having spurs stru-:lr up therefrom at the outer sides of said flanges to hold the latter from collapsing Yand adapted `to anchor the plug in the plastic body, said plug being adapted to receive the end of a nail in said wedge-shaped throat, whereby to wedge said nail therein and bind the plug in the plastic body.

In testimony whereof, l have aiiixed my signature in presence of two witnesses.
